IPAD wont restore "This device isn't eligible for the requested build" With ITunes 10.6.3
I am helping my aunt restore her Ipad to default settings after she accidentally changed the password. I turned off the IPad, held the home button, and plugged it into her computer. A box came up with Itunes detects a device in recovery mode but you must restore the I Pad before it can be used. I clicked ok then Restore. A new box came up saying are you sure, everything will be erased and updated. I clicked Restore and Update. The computer says extracting software... but when it is about __ percent done it says "The iPad "iPad" could not be restored. This device isn't eligible for the requested build" I checked out the most common reasons for this error and her I tunes is running a10.6.3. I tried the other trouble shooting methods but she does not know her password for her computer and I dont know enough about apple computers to mess with the firewall. Could someone tell me how I might fix this issue?
